CISTERN ATTACHMENT FOR WATER CLOS ETS.

SPECIFICATION forming part of Letters Patent No. 306,072, dated October7, 1884.

To all whom, it may concern:

Be it known that I, JAMES FoLEY,of Brooklyn, in the county of Kings andState of New York, have invented an Improvement in Cistern Attachmentsfor ater-Closets, of which the following is a specification.

In my Patent No. 282,876, August 7, 1883, a variable pneumatic chamberis shown for causing the cistern-valve to close gradually, therebyallowing the water to run from the cistern into the closet duringthetime that such valve is closing. The variable character of thispneumatic chamber arises from the difference of time occupied in themovement of the piston according to the size of the airinlet. I combinewith the variable pneumatic chamber a cistern-valve of peculiarconstruction, that allows a preliminary wash to be admitted to thecloset, and then the valve may remain elevated while the closet isoccupied, with but little loss of water, and then the valve is allowedto open fully and to close gradually when the pull on the valve by thecloset-seat or bya platform is relieved on rising from the closet.

In the drawings, Figure 1 is an elevation representing the improvementas applied on a cistern. Fig. 2 is a section in larger size of thevalve; Fig. 3, of the pneumatic chamber; and Fig. 4 is a plan of thevariable chamber.

The pneumatic chamber consists of the cylinder a, having legs orsupports I2, by which it is attached to the wall or other convenientplace. The cup-leather piston c is within the cylinder a, and thepistonrod (Z passes through the head 6, and is connected to the rod orchain f, leading to the lever g of the cistern 7a The cook orscrew-valve i in the bottom head, k, can be adjusted to admitatmospheric air with more or less rapidity, and there is an arm, d,extending laterally from the upper end of the rod (1, and to this arm awire or chain, Z, is connected and passes to the seat of the closet, toa platform, or to the closet-pull. When this chain or wire Z is drawndown, the piston c is easily moved, because the cup-leather closes awayfrom the sides of the variable chamber to allow the confined air to passby freely ;hence the cistern-lever g is drawn down the valve raised; butwhen the wire Z is liberated the weight and valve fall but slowly,because the atmosphere can only draw into the variable chamber below thecupleather piston as the valve '5' admits it to pass in. There is atube, in, suspended from the weighted end of the lever g by a wire orchain, it, and hail. This tube on passes into a tube, c, that goesthrough the bottom of the cistern, and is provided with a flange andvalve seat, t, around the tube at the inside of the cisternbottom, andwith a clamping-lump, below the cistern-bottom. This tube 12 is madetight with the cistern by suitable cement or washer. The pipe q, leadingwater to the closet,is connected with the lower end of this tube 2; by acoupling or solder. There is around the tube at and over the seat tthecylindrical valve 0", that rests at its lower end upon the seat 16 whenthe valve is closed. The valve-cylinder r is longer than the part of thetube 12 that rises in the cistern, and the upper end of r is contractedand fastened to or made with the tube m, and the weight 8 gives thenecessary pressure to close the valve to its seat. In the tube m thereare one or two long slots, and in the tube 1; there are correspondingslots or ports; but they are shorter. The parts are made andproportioned so that the slots in m and e coincide when in their normalposition; but as the valve r is lifted off its seat the ports in o areclosed by the tubular portion of m being drawn sufficiently high tocover and close these openings in 1;; hence when the valve is beinglifted off its seat the water rushes, as a preliminary wash, through theslots in the tubes into the closet; but when the valve 7 and tube'm havebeen fully lifted the water is cut off and so remains until the valvebegins to descend, when the slotted portion of o,coinciding with theslotted portion of m, allows the water to run freely to the closet untilthe valve r reaches its seat It and excludes afurther sup ply to thecloset. The screw 12 keeps the tubeslots in theirproper position inrelation to each other, and limits the upward movement of the tube m. t

This valve and cistern attachment is very simple, efficacious, and notliable to become out of order. The tube m, being open at the top, mayserve as an overflow to the cistern.

I claim as my invention- 5 1. The combination, with the cistern, of avalve, 1", the tube '0, and the slotted tube m within the tube 12, achamber, a piston and rod Within the same, and a lever connected to thepiston-rod, substantially as set forth.

1o 2. The combination, with the valve 0', of the slotted tube m, thetube 12, to pass through the bottom of the cistern and provided withslots or ports, and the valve-seat 15 around the tube 12, substantiallyas set forth.
